Another object is to provide the inner side of Th furring block may beformed of any suitthe nail head with projections so formed and arbl t it preferably comprises ranged as to avoid cutting or weakening of apressed fibrous material, such as paper treated W re e a d t by eitheron driving the nail with oil or wax or other suitable liquid to renderinto en a m nt wi h th W e or after the Wire the block impervious tomoisture. While the 5 furring block D may be of any suitable contour, itis preferably formed with substantially fiat parallel end faces andsubstantially of the contour of a pentagon.

The essence of the invention resides in forming the under side of thenail head B, being the side thereof presented toward the furring blockD, with a series of spaced protuberances i of spheroidal contour; fiveof such protuberances being preferably provided spaced equidistant apartand also spaced from the periphery of the shank A on centers to affordgaps 8 between adjacent protuberances to afford a continuousuninterrupted substantially flat surface 9 on the under side of theheads B and extending between the latter and the protuberances I. Thecenters of the protuberances I are spaced equidistant from the axis oftheshank A and being spaced equidistant apart are thus disposed at thecorners of a pentagon. The margin of the nail head is preferably in theform of a pentagon with the corners rounded at the bases'of theprotuberances l. The protuberances I .are presented toward the adjacentend face of the furring block'D-and within the boundary of the latter sothat they may be brought to bear on or be. imbedded in the block.

In the application and operation of the invention the furring nails aredriven into a backing wall E or other suitable supporting structure in ausual fashion with the furring blocks D seating on the surface of thewall E and with a wire mesh- F seating on the furring blocks andarranged with portions of the wire lengths or strands thereof inclose-proximity to the shank ofthe nail, as particularly shown in Fig.2. On thus positioning the wire mesh the nail is driven tobring: thehead thereof tightly against the wire lengths interposed between thenail head and the furring block which latter being yieldable iscompressed beneath the wire engaged by thehead so that such portion ofthe wire will be imposed on and partially-imbedded in the furring blockas particularly shown in Fig. 4.

On thus driving the nail head against the wire to. force" the latterinto the yielding furring block certainof the-protuberances I will bepositioned astride one or more of the strands of'the Wire nettingasindicatedindotted lines in Fig. 2, the. wire thusstraddled by theprotuberances 1ying in a space-8 and seating on surface 9 of the nailhead in close contact with the latter.

By reason of the spheroidal contour of the'protuberances I and theirspaced relation to each other and also by the provision of at least fiveof the protuberances on the nail head no care need .be taken in drivingthe nail in order to effect positioning of .at least a pair of theprotuberances encircling the shank A- astride a wire, and since in eventa wire should happen to be positioned on the furring block such that itmight initially contact a protuberance I to one side of the axis thereofthe rounded contour of a protuberance will present an inclined face tothe wire such as to exert a wedge action thereon and thereby force thewire laterally into the space between a pair of adjacent protuberances.It might occur however that a protuberance may occasionally seatdirectly on a wire in which event the portion of the wire so arrangedwill be forced deeper into the furring block but since there are atleast three intersecting strands of wire at the juncture of adjacentmesh of woven wire with two of such intersecting wires divergingrelative to eachother, forming a crotch within which the shank of thenail is positioned, at least one of the wires will be positioned betweenthe shank and one of the protuberances which with the inner portion ofthe wire imbedded in the furring block securely holds-the wire againstbeing withdrawn-laterally outof engagement with the furring nail. Theprotuberances being rounded and the blocks being yieldable, no injury toa wire willbe occasioned in event of seating of a protuberance thereon.

By thus securely engaging the wire mesh between the nail head and thefurring block its accidental disengagement from the furring nail duringthe operation of fastening the wire mesh in-spaced relation tothesurface of the supporting wall is obviated, and applying of the wiremesh may be accomplished with greater facility and speed than where theordinary furring nails are employed; furthermore the anchor of the wiremesh afforded by the protuberances 1 insure against accidentaldisengagement of the wire mesh from the furring nails under the strainsimposed thereon in applying plaster thereto.-

1 claim:

In a furring nail embodying a nail formed with a shank and a head, and asolid furring block through which the shank of the nail extends havingits marginal portion projecting outwardly beyondthe margin-of thenailhead; a series of spheroidal protuberances on the side ofthenailhead presented toward the contiguous end face of said block; saidprotuberances being spaced apart relative to eachother and also beingspaced from the nail shank and thus being adapted-to either extendalongside a wire interposed lengthwise between said head and block or toseat thereon and impress the wire into the surface of theblock tohold'the wire against lateral displacement relative to said block andhead;
